I installed a Tru-Center on my 2012 Monaco and used it for about 6000 miles, then took it off. It will do absolutely nothing to improve handling, and in my opinion the additional steering effort it requires made it harder to drive. It was only beneficial when there were constant side winds or road camber on a straight road and the trim feature would assist in holding the steering wheel against it.
